STUD'ND-SOCKETTYPEFASTENrNG.

VThis invention has tor'its" object to p ro-f vide an improved stud and-socket typeias-v `Vtening of the kind in which an expansible element in one part is adapted to engage `detachably another part. 4Fastenin'gs;of the lkind are employed ferai varietylot purposes, such as articles otdre.ss, and motor and other vehicle"hoods-andk covers.

Theinvention comprises the construction 'ofthe expansible velenicnit `from. tvvo separate pi-cces'wliich are embraced a Wire or other flexible ring, or are-otherwise connected together, and the arrangement Within the said pieces of an axially-movable pin whereby the operative endsfoit the pieces can e);v panded.

In particular the invention con'iprises aY tivo partf 'fastening comprising" the combina-- tion and arrangementot` parte hereinafter described. I f

In thevapplication ofthe invent-ion to a two part fastening for a shirt cuit as shown in Figures 1-7. one of the parts a is' made from sheet metal in the 'forni ot av flanged button which can be inserted through the hole in one side of the cuff. Likewise the other part o is adapt-ed `for attachment to the other side of the cuff. The button a is formed with a recess or Vsocket presenting n, .shouldered edge c or internal projection which 'can be detacliablyengaged theqexpansible element contained inandproject-v :ing from the other bu-ttontb-i` The -expansi-bleelementconsists of af pair `of similarpieces 'e which when .placedtofgether'have' at one end arslight-'bulbous envsocket.v `Near the otherend .a lange -is formed on the-pieces: andthe periphery of @mc E; f Y i largement"f which canfenter the VVaforesaid :the flange. is groovedjforthereception 'of L arspringfwire ring ."g'ivhi'ch embraces the :fpiecessandfholds?them together. AThe ring #also allovvsthe pieces to moverelativelyvzso `that ff the bulbons end can be expanded or contracted. -The expansible kelement lies ypartly' AWithin .theflnitton7 but the bulbous end `'projects beyond the-same' as shown in Figures'land 5. l

'Forexpand ng and contracting. the two pieces a, an axiallyfshdablepin his used,

and acentralhole is formed inthe Vpieces te 'accommodate f the pin. For-a ,partlot its flengtltl the pin is made oi,smaller,diameter .than the forward;end,fan d the latter isfsuch that when it lies between the pieces it presses the -bulbous ends ofthe pieces apart Y:as

shown 4in Figureslv and 5.` But when itis pressed beyond the; pieces as shown in Fi gure 6,'the -bulbousfends are .closedatogether by the .sprmgrmg f y'The pin" Z1, passes-through tol the .outer side Y I ofthebuttonqb ,and is .provided withja head 7c which can be gripped Jfor pulling the pin outwards. Also the pin is provided with a shoulder Z for expanding theparts e,and

adjacent to the shoulder, a swelling' m is' formed on the stem, the swelling being ar ranged yto (so-operate with a Wire spring p which is similar tov that described again later and shown in front elevation at Figure 10. Zhen the pin is pressed inwards as vshown in Figure 5, the shoulder Z causes the kparts e to be separated orV expanded as shown in Figure 5, and the pin is held against ac cidental Withdrawal by the engagement ofl the Wire spring p with one sideof the swelling m. On pulling out the pin so that the shoulder Z is disengaged from the parts e, theA forward end of the parts e isallowed to contract under the action of the spring ring g. The Wire spring p then engages the other 'side of the swelling m. By the action of the f spring p on the swelling m the pin is held against unintentional movement. y

lThetvvo parte ot the `fastenings above described are connected by placing them to gether so that theexpansible element-on the one enters thefsoolret in the other, and the parts are locked together by the engagement i of the bulbous end oi.Z the .said element with the shouldered edge ot the socket.

moved either by pressing' it'inwards, in the one forni, Yor pulling it outwards in7the l()v other form. i

The applicationlot the invention to other 4uses is essentially the saine as that above described7 theexpansible element and the meanstor actuating' the saine being in all casesy substantially the saine. `Thesubordinate constructional details ot the invention can be varied'rin a number ofways to suit 'the purpose for which it is 'required One application ot the inventionto a'button fastening for use in conjunction with the hood or cover of a motor vehicle, is shown 1n Figures 8-12. Herethe pieeeseare held vtogether by a ring o made :trom sheet metal v 'and formed with .a number of resilient linger pieces which embrace the parts 6.1 The forward end ot the pin h by' engagementwith the interior of the parts e serves to expand them as shown inFigure 19. Withdrawal of the pin allows the parts c to be contracted or closed together as showni'n Figures 8 and 4l1.- VAXial'I-novement of the -pin in either direction is limited, and the pin is held against accidental movement by the engagement oi avwire spring pwith eitherof a pair of grooves g in the pin, the part intermediate to thevgrooves being made of aroundedvor bulbous form as'shown in Figure 9, so the pin may be movable by aXial pull or pressure between thel portions of the wire springr p whichengage the pin. Figures 8 and 9 show y material.

E. pansion of the bulbous end is etl'eeted'by the sliding pin. 'lo release the parts the pin is a pair of main parts@ 71eachadapted to be securedto a pieceot' fabric or othery iiernble ticularsthe fastening is essentially the saine asthose already described.

Having' thus described my invention what l' claim as new and desire to secure bylietters Patent is i 7 Y 1.-.In stud .and socket typ the kind speoihed, ,the combination comprising artwofpiece expansible element,resilient means for connecting' the `two pieceso't the said element,l and an axially movable. pin

l It desiredkthe part a mayy beV 'adaptedto' be secured tothe wood or other l.trame work of rthe vel'ncle- In other parwherebyl the operative ends of the said pieces holding the twoV pieces of the said element together, a pin adaptedby axial movement to expandorpermit contraction of thesaid aimed in claim 1,'V

element, a swelling on the pin, andV a wire f spring adapted to engage the pin at either side of the swelling for preventing unintentional movement of the pin, substantially as described.

In testimony whereof I have signed-my name to this specieation.
